Police said the couple went to the Longbranch Steakhouse near 86th Street and Marshall Drive for dinner last week. The man tried to take something out of his pants pocket and the gun he was carrying went off, hitting his wife in the leg.

The woman was treated at a nearby hospital and released.

"It was purely an accident," said Lenexa police Officer Dan Friesen. "Just good weapons handling and safety would go a long way. He had a small-caliber pistol in his pocket without a holster or a sheath. You need to use a holster to protect the trigger from being activated."

Police said the man had a permit to carry his concealed .380 semiautomatic pistol. Under Kansas law, it's not illegal to carry a weapon inside an establishment unless there are signs posted to indicate that weapons are not allowed.

The Longbranch Steakhouse allows people to carry concealed guns in the restaurant but it said it may revisit the policy. The owner said the restaurant was fortunately not very busy at the time of the shooting.

Police said the case has been sent to the Johnson County District Attorney's Office for further review. The state will determine whether the man's conceal-carry permit will be revoked.
